Abstract

A molding equipment and method to mold stackable inter-engaging bricks, blocks, stones and the like and bricks, blocks, stones and the like produced therewith are disclosed. The molding equipment comprises a main structure which contains individual cavities. Each cavity preferably has a middle structure to which a brick separating element can be attached. Without the brick separating element, each cavity can form two attached splittable bricks whereas with the brick separating element attached, each cavity can hold two individual smooth or embossed face bricks. The size and shape of the stackable inter-engaging bricks is such that once out of the mold but still in an uncured form, the said brick can stand on its side without falling down, being damaged, buckling or being otherwise deformed during the manufacturing process.

Description

Title of invention
A molding equipment and method to manufacture stackable inter-engaging bricks, blocks, stones and the like with a smooth or embossed face.
Field of invention
The present invention relates to the field of stackable inter-engaging bricks, blocks, stones and the like for building niortarless walls. This invention relates more precisely to the process of manufacturing individual smooth or embossed face or attached splittable inter-engaging bricks, blocks, stones and the like. As used herein, the word "bricks" also refers to blocks, stones and the like.
Background of the invention
Stackable inter-engaging bricks are used to build mortarless walls and this is known in the art. Wall building blocks which may be stacked and interlocked without being held together by a binding agent such as mortar are known. One such block has a top face which comprise a tongue element and a bottom face which comprise a mortise element. Both elements are configured in such a way that when two blocks are stacked, the bottom face of a block engages with the top face of a like block disposed below while the top face of the block engages with the bottom face of an above- disposed block. An example of such a block is shown in U.S. Pat. No. 6,108,995 (Bouchard et al.).
In the process of manufacturing stackable inter-engaging bricks, multiple attached splittable bricks made of brick material such as concrete are first cast in a metal mold. The molded attached brick units are then extracted from the said mold and conveyed through the manufacturing plant on steel or wood plates. The molded attached brick units are then cured in kilns in order to cure the said brick material. Once cured, each of the attached bricks are detached in the middle in two individual split face bricks by the mean of a known splitting equipment. In this embodiment, every molded attached brick unit can produce two split face bricks.
The reason for manufacturing two split face bricks from a single attached splittable brick unit is found in the fact that, prior the completion of the curing procedure, an uncυred single brick would be too fragile to be conveyed in the manufacturing plant without being unacceptably damaged or deformed in the process. Conveying uncured individual prior art bricks would result in an increase of defective or rejected bricks.
Also, the process of cutting attached brick units into individual bricks causes the bricks to have split faces, which may not be always desired.
There is thus a need to find a mean by which stackable bricks could be molded, conveyed and cured individually without being damaged or deformed unacceptably and in such a way that the resulting brick faces could be smooth or embossed.
Object of the invention
Accordingly, an obj ect of the present invention is to provide a mean by which stackable bricks could be molded, conveyed and cured individually without being damaged or deformed in the process. Another obj ect of the present invention is to provide a method to manufacture two individual bricks in a single mold cavity without the need for a specialized cutting equipment.
Another obj ect of the present invention is to provide molding equipment that can mold smooth face bricks while molding the said bricks.
Another object of the present invention is to provide molding equipment that can mold embossed face bricks while molding the said bricks.
Another object of the present invention is to provide molding equipment that can selectively mold individual smooth face bricks, .embossed face bricks or attached brick units (which are to be cut further in the manufacturing process).
Another object of the present invention is to provide molding equipment to manufacture smooth or embossed face bricks which are cheap to manufacture.
One more object of the present invention is to provide molding equipment to manufacture smooth or embossed face bricks which are easy to manipulate.
Other and further objects and advantages of the present invention will be obvious upon an understanding of the illustrative embodiments about to be described or will be indicated in the appended claims, and various advantages not referred herein will occur to one skilled in the art upon employment of the invention in practice.
Summary of the invention
To attain these and other objects which will become more apparent as the description proceeds. According to one aspect of the present invention, a method to manufacture both individual smooth or embossed face bricks or attached splittable bricks is provided. Each of the bricks has a tongue interlock element and a mortise interlock element configured in such a way that the bricks are in a mutual engagement when bricks, blocks or stones or the like are stacked one of top of the other.
Molding equipment in accordance with the present invention comprises a mold having at least one and preferably a plurality of cavities. Each cavity allows the formation of a pair of splittable bricks.

Detailed description of the preferred embodiments
With reference to the annexed drawings, the preferred embodiments of the present invention will be herein described for indicative purposes and by no means as of limitation.
The drawings and the description attached to it are only intended to illustrate the idea of the invention. As to the details, the invention may vary within the scope of the claims. So, the size and shape of the individual stackable inter-engaging brick (1) (figure 6) may be chosen as desired, as long the said size and shape enable the said individual brick to stand on its side uncured as shown in figure 6 without falling over, being damaged, buckling or being otherwise deformed during the manufacturing process.
For example purpose only, referring to figure 6, a single individual stackable inter-engaging brick (1) with the side-section shape (3) shown will stand 'on its side uncured without falling over, being damaged, buckling or being otherwise deformed during the manufacturing process if the side-section area (3) to the brick length (2) ratio is 26.65:1. However, given other brick characteristics such as brick material, brick shape, brick side-section inertia momentum and brick length according to figure 6, the ratio would be different.
Referring to figures 3 and 4, the molding equipment main body (10) is illustrated. Several cavities (12) are created in the molding equipment main body (10). The cavities (12) are used to cast the concrete or other appropriate material to produce bricks (not shown here).
Figure 3 shows molding equipment for producing splittable brick units. However, in figure 4, a brick separating element (11) has been attached to the mold (12) (see figure 3) at attachment points (20)- and (21). The said brick separating element (11) attached at said attachment points (20) and (21) thus creates two separated cavities (13) to mold individual smooth or embossed face bricks.
Figure 12 shows the brick separating element used to manufacture individual smooth face bricks. The upper part (30) of the said brick separating element has openings (31) at both ends of the said upper part to secure the said brick separating element to the molding equipment main body (10) (see figures 3 and 4). The brick separating element may have several brick separating plates (32).
Figure 13 shows the brick separating element used to manufacture individual embossed face bricks. The upper part (30) of the said brick separating element has openings (31) at both ends of the said upper part to secure the said brick separating element to the molding equipment main body (10) (see figures 3 and 4). The brick separating element may have several brick separating plates (33).
Referring to figures 12 and 13, smooth (32) and embossed (33) brick separating plates are illustrated. The said smooth (32) and embossed (33) brick separating plates have "V" shaped grooves (34) on each side to secure each brick separating plate (32)/(33) in the molding equipment main body (10) (see figures 3 and 4).
Although the molding equipment and method for molding stackable inter-engaging bricks with smooth or embossed face has been described with a certain degree of particularity, it is to be understood that the disclosure has been made by way of example only and that the present invention is not limited to the feature embodiment(s) described and illustrated herein, but includes all variations and modifications within the scope and spirit of the invention as hereinafter claimed.
